MOORESVILLE, IN (WXIN) -- A family vacation to Florida resulted in a week in the hospital for one Indiana family. Their 12-year-old daughter Kylei contracted a life-threatening infection from the beach.

“It's just so hard seeing friends and family on the beach having fun because we were there doing the same thing, and I almost lost her,” said Kylei’s mother Michelle Brown.

Towards the end of their trip to Destin, Florida this month, Kylei began feeling pain in her leg. When the family got back to Indiana, the pain turned into swelling and then a fever. Brown called and made an appointment with her doctor, but she didn’t realize how bad the situation was until the doctor directed them to the emergency room.

"When they told me we needed to go home and pack bags and get to Riley, my anxiety went from 0 to 110," Brown said. "I knew something was wrong.”

Brown said doctors first thought it might be a blood clot. She watched in horror as her daughters’ condition got worse.
